Hi, I have an E-PL1 on order and was browsing for lens. Two interesting lens, I found, are: - Electrophysics / Astroscope 25mm f0.95 - Navitron 50mm f0.95 The former sells for $448 at B&H and Adorama. The latter is listed for $1500 on ebay. Unfortunately, I could not find any reviews to justify their costs. Has anyone tried either lens and what might be a fair value for them? (while we wait for Nokton 25mm to be available again) Thanks!
